does anyone know what format the 3d video is for the uncharted 3d trailer? should i set my tv to stereoscopic or checkerboardkrayzieE99

It's a full resolution 720p frame-sequential (L1-R1-L2-R2-...) MP4 video encoded with 3D tags. Playing the video from the PS3 XMB prompts you with a "play in 3D?" option. If you select Yes the PS3 changes video output from regular 1080p or 720p 2D to 720p frame-packed 3D. The PS3 video player then takes two frames (L-R) at a time from the MP4 and outputs them in one packed (super-sized) 3D frame. This is the "true" HDMI 1.4 3D video format. The TV should detect this as the PS3 sends the correct HDMI 3D control data and change to 3D mode automatically. You don't have to select any 3D setting on the TV at all.

BUT: You need to download the 3D specific videos (there are two U3 videos and each has a 3D and a 2D version), AND you must have already updated the PS3 to support 3D (v3.50 or later is best).

There are other 3D videos available in the PSN store including MotorStorm Apocalypse, Virtua Tennis 4 and The Fight: Lights Out so be sure to check them out too.

• Which PS3 games support 1080p, and which support 3D?

There are almost 40 3D games so far and over 20 known 3D games coming:

3D PS3 Games

There are few true 1920x1080p games (around a dozen retail games, less than 20 PSN games):

HD PS3 Games

You won't see many 1080p 3D games on the PS3 (there are none at present) because:

a)The current HDMI standard (that the PS3 HDMI chip has bandwidth for) is 1080p at 24Hz (24 frames per second) which is just too low for smooth gameplay in most games. It might be possible with 1080i but for now the best 3D game resolution is 1920x1080p half-resolution, like side-by-side making it 960x1080p per eye but it isn't supported in any PS3 game as Sony has pushed using HDMI compliant 3D formats, 1280x720p for 3D at up to 60Hz. The half-res formats are not in the HDMI spec but all 3DTV's support it. All 3DTV's can auto-detect the HDMI standard 3D modes but few can auto-detect the half-res modes. 960x1080p is slightly better than1280x720p.

b)3D requires more processing which means that it is difficult to squeeze out enough performance to get both 3D and full HD. It might be possible in games with simple graphics.

Also, if you have expertise regarding the following questions, please answer:

• Does a PS3 game generally look better in 1080p than in 780p or 1080i, or is the difference minimal?
• What is the quality of the 3D in any 3D games you mentioned?

Like upscaled DVD video a game that is not Full HD will look slightly better when upscaled but it's a marginal improvement. Many of the 1080p native games disable anti-aliasing so the trade-off means that you don't get the full benefit of the higher resolution.

The 3D in games varies greatly. It's poor in Crysis 2 (fake 3D), ok in Top Spin 4, good in MotorStorm 3D Rift and Apocalypse, great in GT5 and Super Stardust HD. I mostly agree with the scores in the 3D PS3 games list at the site above.

You need a 3D TV for all except a couple of "anaglyph" (colored glasses) games, mostly released before 3D TVs were available. Check the listing at the following site for the "non-native" ones that you don't need a 3D TV for:

Depending on which 3D TV brand you buy the glasses can be as cheap as $80/pair (Samsung, depending on the retailer) but most are in the $120-$200 range.

Most TV's come with at least one pair of glasses (check before you buy) and there are frequently free promotion bundle deals that include up to 4 additional pairs. A free Sony 3D TV bundle recently included a PS3, glasses, games and movies!

If you're in the market for a new TV then 3D is a no-brainer (unless you want to wait a year or more for a full-res polaroid 3D TV that uses cheaper glasses or a reasonably priced glasses-free 3D TV withi limited viewing angles and lower PQ). If you're not then it is a large expense. Most 3D TV's cost $100-$400 more than an equivalent 2D model. Be wary of buying the latest generation, they're very expensive and have little benefit in most cases over the previous gen.

I hope that helps.
